Hrm, new project... to install an ltsp server to a usb stick, and then in order to prevent the stick from being overused, to boot it with init=/boot/init-ltsp, in ro+tmpfs+cow mode...
08:23
:)
08:23
And, to use the stick itself as the image to be published
08:24
i.e. nbd-server will directly serve /dev/sda1
08:26
<Hyperbyte>
alkisg, why not go all the way and PXE boot from the cloud? ;-)
08:28
<alkisg>
It would be nice if we had gigabit internet connections :)
08:32
<Hyperbyte>
We do. :-)
08:37* alkisg wonders if LTSP, LDM etc work fine with SERVER=localhost
08:48* alkisg loves ltsp-pnp, a dpkg-reconfigure grub-pc; init=/sbin/init-ltsp was all that was needed to get cow+LDM instead of lightdm :)

08:59
<alkisg>
And an LDM_SERVER=localhost plus a small bug fix away, it's possible to login with the existing users in a temporary environment
08:59
Best live cd ever!!! To customize it all you need to do is boot without init=/sbin/init-ltsp...
08:59
*live usb stick

<elias_a>
alkisg: Nice to know & hear! :)
09:11
<alkisg>
I'll write a tutorial for that when I finish it...

Haha, implementing autologin in the live usb stick is now as easy as LDM_AUTOLOGIN=administrator...
09:25
No need for casper, liveboot and other packages

The client successfully booted and logged in!
10:06
All that was needed was an /etc/lts.conf on the "server" (=stick), and to modify one line in the ltsp sources

Hello, I just started using epoptes and would like to know how to add a computer
16:47
Hi someone there?

<alkisg>
vagrantc: I installed ubuntu + ltsp on a usb stick normally, like I would install it on a hard disk. Then, I put this in /etc/lts.conf: https://paste.debian.net/312227/
18:24
I also symlinked /opt/ltsp/images/i386.img to /dev/disk/by-uuid/path-to-the-stick-partition, and /opt/ltsp/i386 to /
18:24
Now I'm able to do the following:
18:24
1) To boot the stick normally, like I would boot an external hard disk, to install packages in it etc
18:25
2) To boot it in cow mode, by just adding `init=/sbin/init-ltsp` in the cmdline (dpkg-reconfigure grub-pc to make it permanent). This prevents the usb stick from wearing out from frequent use.
18:26
Then this is an ltsp server, I can serve the usb stick partition to multiple clients in the network. No need for an additional /opt/ltsp/images/i386.img, I'm serving the whole partition.
18:27
3) I can have a [mac:address] section in /etc/lts.conf for some client that doesn't have enough ram, and disable a whole lot of services. This allows me to boot a recent distro in a client with 128 MB RAM!
18:28
So, editable stick, cow stick, ltsp server, very light stick... 4 in 1 :) And all that's already supported with upstream LTSP code, except for a few INIT_COMMANDs that need to be ran until a couple of small things are fixed upstream :)

Hello every1...I'm getting "PXE-E61: Media test failure, check cable" error on 1 client while others boot w/out issue.
20:51
<maldridge>
tubaclarinet: sounds like the cable is unplugged
20:52
<tubaclarinet>
That's what I thought too, but it is plugged in
20:52
<vagrantc>
bad cable?
20:52
bad port on switch?
20:52
bad port on client?
20:53
<tubaclarinet>
Port is fine...works with Windows
20:53
afk

<vagrantc>
dhcp not configured to give any leases to that mac address?
21:05
broken PXE stack on the client?
21:06
is it plugged into a switch, or directly to the server? if plugged in directly, autonegotiation of the link status may take longer than PXE is willing to wait...

A thousand pardons...i had to step away from my desk
21:14
I forgot 2 mention that I am using LTSP-Live on Edubuntu
21:15
I thought I read somewhere that LTSP-Live can support only up to 8 concurrent clients...is that true?
21:23
<vagrantc>
it entirely depends on your hardware ...
